Now THIS is an odd duck....so to speak. From today's San Francisco Chronicle:

SOLANO -- As if crop circles weren't proof enough that extraterrestrials are among us, an alien has now been found in the stomach of a duck.

That, at least, is the conclusion reached by workers at the International Bird Rescue Research Center in Cordelia (Solano County) when they viewed an X-ray image they took of a sick mallard.

Right there, in the duck's ventriculus, or gizzard, is the shocking image of a grimacing, bald-headed being. How it got there, nobody knows, but when an autopsy was performed after the bird died of unrelated causes, the alien had mysteriously disappeared.

"We're a 35-year-old organization, and we've seen a lot of things -- bullets, fish hooks -- but this is the first time anything like this has shown up," said Jay Holcomb, executive director of the bird rescue center, which was founded in 1971 after an oil spill beneath the Golden Gate Bridge. "I don't know my aliens well, but it looks like one of those with the big eyes and the long fingers."

The drake in question arrived at the center Sunday with a broken wing. Workers do not know how the mallard was injured, but it was clearly weak and emaciated. In an effort to pinpoint the trouble, Maria Travers, the assistant rehabilitation manager, took a radiograph image of the bird. She was stunned by what she saw.
